To all chasm it mali/concern: e t t 1 `Be itlriiownI that I, MALooLM SooUGALE, a

H citizen of theUnited States, residingat Weatherford in the county of Parker and State of Texas, have invented new andujseful Improvements in Pencil-Sharpeners, foi whiclithe :following isa specilication.` t l This invention relates `to stationery, parti cularly to pencil Sharpeners, and has for its object the provision of a pencil Sharpener so constructed as to form a` concavity in the end of a pencillead so as `toiproducea circular writing edge,all points of `which may `be used and which will consequently ,i bea distinct improvement over the ordinary .pointy commonly c formed byi` `the "ordinary pencil Sharpener and which `so` comes dull. .i y An important objectisthe provisiono a device of this character which will be simple and inexpensive in manufacture, highly efiicient in use, durable in service, anda quickly hegeneral improvement in the art.

With the 'above and other objects and advantages in' view, the invention consists in the details of construction to be hereinafter more fully described and claimed, and illustrated in the accompanying drawings in,`

Figure 1 is a side elevation ofa pencil sharpener constructed in accordance` with my invention, Fig.` 2 is a longitudinal sectional view therethrough, i

Fig. 3 is an enlarged longitudinal Isec-` tional view through the end of a pencil sharpened by means of my device, and t Fig. l is a longitudinal section `through a modiiedform. v Referring more particularly tothe drawings, the letter A designates a pencil and B designates the so-called lead thereof. y

In carrying out my invention I `provide a Sharpener formed as a shell 10 which includes a cylindrical portion 11 and a tapered portion 12. Located within a slot 13 inthe i tapered portion is a cutting blade 14C which is inclined and which is adapted to shave away the wood part of the pencil andalso a portion of the end of the lead. Qrdinarily sliarpeners of this character form a point at the end of the lead.

The important feature of my `invention is the provision oit' a cutting member operating m against the end of the lead for `forming ai concavity therein, and in actual practice this ,Patented though in the present instance I have shown la `screw im 15 threaded into the end` of the tapered" portion "l2 `of the shell, having a knurled or millednadjusting head 16 `land having its point 1'?` formed with a `cutting' .blade similar to that of a counter-sink.

sharpeningfa pencil `by means of my device, the operation is the same as that of any other Sharpener, it being noted that my TATTNT OTTTCT y jmay be accomplished a variety of ways .device is preferably provided with a handle f `18 facilitating` its engagement by the operatorsfingers.` `As the pencil is sharpened thei'en'dl'portionol the lead will be shaved away` slightly at the sides and at the same time aconcavity `19 `will beformed `in the endfof the lead. As shown in the drawings,

-tliisiconcavity conical though it is readily apparent that `it might be cylindrical or ,merely dished if desired, the shape making no difference as the object is to form the circular sharp edges 20, all points of which may be used forwriting. It will be ob-` i of this `shell is a sharpening member 22 which inactual practice I form fromPort- T land cement and ground glass. This member is so shaped that when a lead pencil, which Smay have had its wood portion shaved down by any means, is inserted within the `shell and rotated, the member 22 will operate to form afconcavity in the end ot the socalled lead.

While I have shown and described. the preferred embodiment of my invention, it Vis of course to be understoodthat I reserve thefright to make such changes in the form, construction, and arrangement of parts as y will not departyfrom the spirit of the inven`` tion or the scope of the subjoined claims.

`Having thus described my invention, I 1

claim: y. 1. A device of the character described comprising a shell including a cylindrical 'portion anda tapered portion, the tapered portion being provided with aEslot, an inclined blade located within the slot andproe jecting inwardly of the inner periphery of the tapered portion,`ai handle on saidY shell, and a cutting member located atthe .apex ofthe tapered portion and adapted to pro-Y duce a concavityin the end ofV the lead of a pencil" engaged within thedevice.

2. A device of the character described lcomprising a shell includingV a cylindrical portion and af taperedportion, the tapered portion being provided with a slot, an inclined blade located-within the slot and pro- `jecting ,inwardlyl of lthe innen periphery7 of the tapered portion, a handle on said shell,

anda cutting'member located at the apex of the tapered portion andv adapted to produce a 'concavity in the end of the lead of a pencil engaged within the device, said cut- K `ting member being adjustable whereby to y K eXtend a greater or less extent into the shell.

3. A Vdevice of the character described comprising a shell including a cylindrical portion and aftapered portion, the tapered portion being provided with a slot, an inclined blade located within the slotandpro- A jecting inwardly of the inner periphery of the tapered portion, a handle on said shell,

and a cutting member located at the apex of the tapered portion and adapted to produce a concavity in the end of the lead of a pencil engaged within the device, said cutting member being adjustable whereby to .extend a greater or less extent into the shell and being formed as a screw threaded into the shell and having its point formed with a plurality of radial cutting edges.

A 4C.' A device of the character described comprising a shell adapted to receive the sharpened end of a pencil, and means within lsaid shell for forming a concavity in the end of the pencil lead 5. A device of the character described comprising a shell adapted to receive the I MALCOLM SCOUGFALE.
